Singapore is making significant strides towards promoting sustainable practices in its maritime industry by waiving port dues for vessels using zero-emission fuels or technologies. Effective from January 1, vessels running fully on battery power, hydrogen, fuel cells, ammonia, B100, and green methanol will enjoy a 100% reduction in port dues for stays of four days or fewer. Moreover, ships utilizing conventional methanol, LNG, and various biofuel blends will receive concessions ranging from 20% to 30%. To qualify for these discounts, vessels need to pre-register under the Green Port system and ensure the continuous use of zero-emission technology throughout their stay in Singapore. The initiative aims to encourage the adoption of cleaner energy sources in the maritime sector and reduce emissions. By requiring the initiation of zero-emission technology before entering Singapore Port Limits and maintaining its use during the port stay, the Maritime and Port Authority of Singapore sets a sustainable precedent for other ports globally. This proactive approach showcases Singapore's commitment to environmental sustainability and positions the city-state as a leader in promoting green technology within the maritime industry.
